riboid Posted November 12, 2021 Share Posted November 12, 2021 I've spent so much on insulation and everything that goes with it, not sure if I'll ever recover the costs from a thermal improvement point of view, but, we have assembled a house not only for us, but for future generations too. Good job. Link to comment Share on other sites More sharing options...
Iceverge Posted November 12, 2021 Share Posted November 12, 2021 Energy savings are obviously one aspect. Don't forget the thermal comfort aspects and the protection of the structure you're achieving. Payback only on energy costs are a very narrow window through which to view thermal upgrades.

This is what I keep telling myself when I see the big hole in my finances caused by a hell of a lot of Steico wood fibre products. Link to comment Share on other sites More sharing options...

How I wish more people saw it in that way. Couldn't be more true. It's also healthier and provides a much more pleasurable and comfortable environment to be in, providing it's done right of course. I personally think that due to their mostly passive nature, thermal upgrades are cheap for what you get. Link to comment Share on other sites More sharing options...

Masonry is rarely this without a primer. Is the expensive primer from the tape manufacturer required though, or are there cheaper primers/methods of preparing the substrate? I'm looking at the Winflex-I which needs PHS Ottello Adhesive Sealant to bond to block work, which itself needs a primer. Suspect this may be the cheapest option. Alternative I'm considering are the Isocell Airstop products, or Pro Clima Contega Solido SL though I'm unclear if the latter requires a primer.

(Or rolls of tape per tube of adhesive). Link to comment Share on other sites More sharing options...

I reckon I got maybe 5m of a bead from a tube. This was mainly due to the rough texture of my lightweight blocks. If your blocks are smoother with not many holes then it will go much further. On blocks I cut the nosel much wider compared to when I had to stick the tape to concrete on the back of my window cills. Maybe talking at least double the amount of adhesive coming out of the tube on rough blocks compared to smooth concrete. Link to comment Share on other sites More sharing options...
cwr Posted December 21, 2021 Share Posted December 21, 2021 Thanks Declan, that's good to know. So gonna need a lot of adhesive... I wonder if a parge coat would help reduce the amount needed much. Link to comment Share on other sites More sharing options...
Andehh Posted December 22, 2021 Share Posted December 22, 2021 So all these products are to seal the gaps between window & masonry? Is there a reason gripfil or silicone is not used to plug these gaps up? They could surely achieve a similar result & are much more readily available?

As the walls shrink a tiny bit this adhesive will allow the tape to move so you won't end up with cracks at the joins and in turn air leakage. They are also very very sticky.

Iceverge Posted December 22, 2021 Share Posted December 22, 2021 It's tempting to substitute airtightness products for others when you're building. The difference is only apparent months later. The flexible airtight sealent I used, (blue from a sausage) never really truly sets. Its like chewing gum, nasty if you get it where you don't need it or try to remove it. My brother looked over the scaffolding one day and declared it the worst thing he'd ever worked with such was its limpet like adhesion. Also for airtight tape. It seems to completely weld itself to any well prepared surface. Not instantly, but after a few weeks trying to remove it is almost completely impossible. I was so convinced I used it to seal our shower tray and bath. No leaks so far. I'm sure someone will tell me off.... 1 Link to comment Share on other sites More sharing options...

Iceverge Posted January 12, 2022 Share Posted January 12, 2022 @cwr Try Philip @ https://www.prodomo.ie/ in Tralee. I think he posts to NI. I bought all my airtightness items there. I thought the prodomo own brand stuff was better than the belgacoat stuff i tried too. Link to comment Share on other sites More sharing options...
